Math in Nature

Here's a beautiful short film demonstrating mathematical principles as they appear in nature: Nature by Numbers. In the video, illustrator CristÃ³bal Vila demonstrates how the Fibonacci Sequence is visible in a Nautilus shell, and proceeds through the Golden Ratio, Golden Angle, Voronoi Tessellations, and the Delaunay Condition. (Yeah, I hadn't heard of those last two either.) For more details about the math behind this film, and how the Nautilus example is actually a bit flubbed, read Vila's explanation of the film (in both English and Spanish).

Recommended for: people who like neat animation, easy-to-understand math, and/or something to divert them on a day when not much else is happening online.

Also on Mental Floss:

DID YOU KNOW? Marlon Brando hated memorizing lines so much that he posted cue cards everywhere to help him get through scenes.
He even asked for lines to be written on an actress's posterior. (That request was denied.)
